Power consumption when disable RF for nRF51822

[sunnyjet16]

Hi,

I got a question on power consumption: In my case, I do not need RF functions on most of time. If disable RF function, what working current of nRF51822 would be?

Regards Alex

Have a look at the nRF51822 Product Specification 3.1, available here.

Have a look at Table 32. In System ON the base current consumption is 2.6 uA with 16 kB RAM enabled, and 3.8 uA with 32 kB RAM enabled.

It depends on what peripherals you are using, so it is difficult to answer. You should be able to find the information in the PS.
